CLOSURE FOR JARS.

SPECIFICATION forming part of Letters Patent No. 361,369, dated April19, 1887.

Application filed February 17, 1887. Serial No. 227,952. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH PETrr, a citizen of the French Republic,residing at Bordeaux, in France, have invented certain new and usefulImprovements in Sealing-Caps for Jars and other Like Vessels, of whichthe following is' a full, clear, and exact description.

Figure 1 is a perspective view of the neck of a jar or bottle with itssealing cap or capsule. Fig. 2 is a like view of the neck of the jarwithout the sealing-cap, illustrating the construction thereof. Fig. 3is a vertical transverse section of a jar illustrating my invention.Fig. 4 is-a like view of the sealing cap or capsule detached, and Fig. 5is an isometric view of the unsealing-wire detached.

The objections to the use of tin in the construction of vessels forcontaining preserves, and more especially that class of preserves whichcontain more or less acid, are well known, and many efforts are beingmade to substitute glass vessels for the tin vessels here. toforeemployed. The great difficulty encountered-in the use of glass is inobtaining a hermeticclosure to prevent fermentation and deterioration ofthe material contained in such vessels, and so far as I know this hasheretofore not been obtained, except by comparatively costly andlaborious means.

The object of this invention is to provide a means whereby a hermeticclosure of glass vessels may be readily obtained in a cheap manner, andwhereby the vessel may be as readily opened for removal of the contents.

To these ends the invention consists in the peculiar construction of theneck or mouth of glass jars, bottles, and other receivers for preserves,and in the combination therewith of a hermetic seal and means forremovingthe seal, substantially as hereinafter fully described, and asset forth in the claims.

In the drawings, A indicates the glass jar, and A the neck and mouththereof, provided with a peripheral flange, a, whose upper faceconstitutes the seat for a rubber gasket, and whose lower face forms aretaining-shoulder for the sealing cap or capsule. In the flange a isformed a peripheral groove, a, for the reception of a wire, W, by meansof which the seal of the bottle or jar A may be broken, as

hereinafter described.

The capsule 0 consists of a cylinder of suchdiameter as to'fit over theannular shoulder a, and ofsuch length as to admit of its being bentunder the said shoulder a. The periphery of the capsule O is depressed,the depressed'portion a fitting over the mouth and around the edge ofthe neck of the jar and resting on the rubber gasket G, seated on theshoulder a.

The sealing-cap has in its body on a line registering with the groove(4, or substantially so, an opening, 0, for the passage of the ends ofthe unsealing-wire W.

The mode of sealing and unsealing the jar may be briefly described asfollows, the sealing being preferably effected in a suitable machine: Arubber gasket, G, is placed upon the shoulder a around the mouth of thejar. A wire, IV, of suitable length, is then laid in the groove of saidshoulder. The cap or capsule is now placed upon the mouth of the jar,the ends of the wire W being passed through the opening 0. Pressure isnow applied to the top of the capsule, to compress the rubber gasketuntil the upper contracted portion of the capsule incloses the mouth ofthe jar, when the edge of the sealing-cap is bent in under the shouldera. If desired, the wire may be applied after the sealing-cap has beensecured to the jar, by introducing one end through the opening 0' andpushing the same around the flange a in the groove a until the other endreaches the opening 0. It is obvious that in this mannera hermeticclosure is obtained and the sealing cap or capsule firmly held inposition. The ends of the wire \V may now be twisted or simply bent overthe capsule in opposite directions.

Then it is desired to break the seal of the jar, the wire ends areuntwisted or bent out, and on pulling upon the wire ends in oppositedirections the capsule is cut in two. This may also be effected, and ina much easier way, by forming a loop at one end of the wire andfastening the other end securely to said loop or to the wire, as shownin Fig. 5.

To .cut the capsule, it will be only necessary to insert a suitableinstrument-such as the point of anice-pick, a nail, or an awl-into theloop, and rotate the wire around the neck of the jar, as will be readilyunderstood.

.By means of the construct-ion of neck and capsule described a hermeticclosure of the mouth of the jar is obtained, since the rubber especiallydesigned for glass jars, may be applied to cans or vessels made of othermaterial.

"What I claim is- 1. A vessel provided with a flange encompassing itsopen end near the month, said flange having a groove in its outer face,a ruhbergasket seated on said flange, and a sealing cap or capsulefitting over the mouth of the vessel, the gasket, and the said flange,and having its edge bent under the flange, said cap or capsule beingprovided with an opening in its vertical Wall, in combination with awire seated in the groove of the flange, the ends of saidwire projectingthrough the opening of the cap or capsule, substantially as and for thepurpose specified.

2. As a means for breaking the seal of sealed vessels, the combination,with the vessel and a sealing cap or capsule fitted over the open endthereof and firmly connected therewith, of 30 a Wire arranged around thevessel, under the cap, between the point of connection and the mouth ofthe vessel, the ends of said wire pro jecting through the cap and beingconnected together to form an eye or 100 substantially as and for thepurpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this29th day of January, 1887.
